Sunlight as the energy, solar street lamps use light born v effect principle made solar panels during the day to receive solar radiation and translated into electricity output. Solar photovoltaic system of hybrid power supply system has the following advantages:
systems with high practicability. In the independent system because of the change of renewable energy and unstable which may lead to a power supply system can't satisfy the load demand, there is load power shortage situation, using the hybrid system will greatly reduce the load power shortage.
and use diesel generator system, compared with less maintenance and use less fuel.
higher fuel efficiency. At low load, under the condition of diesel engine fuel efficiency is very low, will cause the waste of fuel. Comprehensive control makes the diesel engine in a hybrid system can work near the rated power, so as to improve fuel efficiency.
hybrid power supply system can also achieve a better utilization of renewable energy. Use of renewable energy independent system is usually carried out in accordance with the worst design, renewable energy is changing, unstable, so the system must be carried out in accordance with the energy to produce the least amount of time. Because the system is carried out in accordance with the worst case design, so in other time, the capacity of the system is too large. Solar irradiation in height of the excess energy can't used and wasted.
load matching of better flexibility. After using the hybrid system, because diesel generator can provide larger power immediately.
so hybrid system widely accept by end users and trust, its application scope will be more and more widely.
